Disc amusement device

Abstract

A flying disc has an outer annular doughnut-shaped hollow ring surrounding a generally planar central portion. The annular ring is permanently inflated to a high pressure. The flying disc is formed of a thermoplastic plastomer or elastomer and is capable of bouncing 20-25 feet after landing, and rolling an additional distance if it lands on its outer edge.

1 . A game or amusement device in the form of a flying disc, comprising:
 a peripheral doughnut-shaped hollow ring surrounding a generally planar central portion,   the hollow ring being permanently inflated to a pressure of at least 0.9 kg/cm 3 ,   the flying disc having a wall thickness of at least 72.8 mils, and   the flying disc being injection molded of a flexible thermoplastic plastomer or elastomer.   
     
     
         2 . The flying disc of  claim 1 , comprising a curved transition area between the planar surface interior and the doughnut-shaped ring, the curved area providing the beginning of a concave shape. 
     
     
         3 . The flying disc of  claim 2  which is symmetrical, both top and bottom. 
     
     
         4 . The flying disc according to  claim 1  wherein said thermoplastic material is selected from the group consisting of a thermoplastic polyurethane, polyethylene, polypropylene, silicone and polyvinyl chloride. 
     
     
         5 . The flying disc of  claim 4  wherein the thermoplastic material is a thermoplastic polyurethane. 
     
     
         6 . The flying disc of  claim 1 , wherein the, doughnut-shaped hollow portion has a height-to-width ratio of about 4.5 to 6. 
     
     
         7 . The flying disc of  claim 1  inflated to a pressure of at least 1.2 kg/cm 3 . 
     
     
         8 . The flying disc of  claim 1  wherein said peripheral donut-shaped hollow ring has a height which is less than the distance between its outer edge and its inner edge. 
     
     
         9 . The injection molded flying disc of  claim 1  comprising said generally planar central portion as a single layer, and wherein said single layer generally planar central portion is integral and unitary with said peripheral doughnut-shaped hollow ring. 
     
     
         10 . The injection molded flying disc of  claim 1  wherein said generally planar central portion is imperforate. 
     
     
         11 . The injection molded flying disc of  claim 1  wherein said generally planar central portion comprises a single layer. 
     
     
         12 . A game or amusement device in the form of a flying disc having a top and a bottom, comprising
 a peripheral doughnut-shaped hollow ring surrounding a generally planar central portion comprising a single layer,   the hollow ring comprising a single layer and being permanently inflated to a pressure of at least 0.9 kg/cm 3 ,   the single layer of said generally planar central portion and the single layer of the peripheral doughnut-shaped hollow ring having a thickness of at least 72.8 mils, and   the flying disc being integrally molded as a unitary device of a flexible thermoplastic plastomer or elastomer.   
     
     
         13 . The flying disc of  claim 12 , comprising a curved transition area between the planar surface and the doughnut-shaped ring, the curved transition area providing the beginning of a concave shape. 
     
     
         14 . The flying disc of  claim 13  which is symmetrical on said top and said bottom surfaces. 
     
     
         15 . The flying disc according to  claim 12  wherein said thermoplastic material is selected from the group consisting of a thermoplastic polyurethane, polyethylene, polypropylene, silicone and polyvinyl chloride. 
     
     
         16 . The flying disc of  claim 15  wherein the thermoplastic material is a thermoplastic polyurethane. 
     
     
         17 . The flying disc of  claim 12  wherein said peripheral doughnut-shaped hollow ring has a dimension between said top and said bottom which is less than a distance between its outer edge and its inner edge. 
     
     
         18 . The flying disc of  claim 17  wherein the doughnut-shaped hollow portion has a ratio of the distance between said top and bottom surface to the distance between the outer edge and inner edge thereof of about 4.5 to 6. 
     
     
         19 . The flying disc of  claim 12  inflated to a pressure of at least 1.2 kg/cm 3 .
